It extends the allowable concrete pour depth by 4 inches, enabling installations in slabs up to 12 inches thick. This adaptor is used where standard Cast-In Device height is insufficient for deeper concrete pours, giving installers the clearance needed to meet project specifications. Licensed fire-stop and construction contractors install this component during concrete formwork or pre-pour preparation on commercial and residential projects requiring through-slab penetration firestop systems.\u003c\/p\u003e\n\u003cp\u003eThis height adaptor fits installations where concrete slab thickness exceeds the standard device range and a full 12-inch pour depth is required. It accommodates both metallic and non-metallic versions of the 3M Fire Barrier Cast-In Device, making it a single SKU solution for mixed-penetration projects. Typical applications include multi-story commercial construction, concrete floor decks, and any project where deep slab pours are specified by structural or fire-rated assembly drawings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExtends allowable concrete pour depth by 4 inches over the standard Cast-In Device height\u003c\/li\u003e\n  \u003cli\u003eSupports pour depths up to 12 inches (304.8 mm)\u003c\/li\u003e\n  \u003cli\u003eCompatible with both metallic and non-metallic 3M Fire Barrier Cast-In Device models\u003c\/li\u003e\n  \u003cli\u003eDesigned for 3-inch Cast-In Device configurations\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.43 pounds for easy handling during formwork installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 3-inch metallic and non-metallic models of the 3M Fire Barrier Cast-In Device in concrete slab firestop assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed fire-stop contractor or journeyman electrician prior to concrete pour. The adaptor must be secured to the Cast-In Device and positioned correctly within the formwork before concrete is placed. Verify that the assembly meets the applicable UL fire-rated assembly requirements and local building code before pouring. Do not alter, cut, or modify the adaptor, as doing so may void the fire-rated listing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight Extension\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Pour Depth Supported\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Device Size\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.43 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051115165498\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: 3M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7000133837\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51343115059506,"sku":"7000133837","price":177.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310527903.jpg?v=1782017058","url":"https:\/\/voomisupply.com\/products\/3m-7000133837-fire-barrier-height-adaptor-3-in","provider":"Voomi Supply","version":"1.0","type":"link"}
